The FBI and San Diego police are asking for the public’s help to identify a young man who robbed a downtown bank Monday morning.

The thief walked into HSBC Bank on Broadway near 3rd Avenue about 11:30 a.m. and handed a teller a note demanding cash. He said that he was armed with a gun and motioned to his waistband. He did not display a weapon, but threatened harm if the teller did not comply, said FBI Special Agent Darrell Foxworth.

The robber was described as white, about 25 years old, about 5 feet 10 inches tall and 180 pounds, with black hair. He was wearing a gray long-sleeve shirt with a white undershirt, dark pants and brown shoes.

Anyone with information is asked to call the FBI at (858) 565-1255, the San Diego Police Department robbery unit at (619) 531-2299, or Crime Stoppers anonymously at (888) 580-8477.
